Title: Process of decorating textile materials
IPC: D06P1/44
Filed: 1955-01-18
Abstract: The process of the parent Specification for decorating textiles by printing or padding with an emulsion of a vinyl or divinyl polymer or copolymer and a high molecular basic compound, together with a compound containing two or more groups capable of reacting with the basic groups of the high molecular compound, is modified by employing, as the compound containing two or more reactive groups, a basic high molecular weight compound containing amino and/or imino groups and epoxy groups.  These latter compounds have a selfcross-linking capacity and also effect crosslinking of the other compounds of the emulsion. They also serve to bind the pigments of the emulsion when present, and are preferably condensation products of di- or poly-amines with an epihalohydrin or dihalohydrin, specified di- and poly-amines being tetramethylene diamine, hexamethylene diamine, dipropylene triamine, g ,g 1 - diaminopropyl methylamine, g ,g 1-diamino propyl ether, diaminopropyl tetramethylene diamine, bis - (g  - aminopropyl)-piperazine and N-(1,6-hexanediamine)-3-pyrrolidone.  In examples: (1) an aqueous solution of sodium salts of sulphonated and sulphinated long chain paraffins is emulsified with a mixture of styrene, acrylic acid butyl ester and acrylic acid and the emulsion is acidified and polymerized at 30 DEG  C.  To the polymer emulsion thus obtained is added a cetyl alcohol-ethylene oxide reaction product an aqueous solution of the acetate of a basic polymer from diethylene triamine, g ,g 1 - diaminopropyl - methylamine and hexene diisocyanate and an aqueous solution of the hydrochloride of a basic epoxy polymer from dipropylene triamine and epichlorohydrin.  The mixture is then acidified with acetic acid and made up into a printing paste with the addition of a red pigment, urea, isooctyl alcohol, methyl cellulose and water, the paste then being printed on cotton, followed by drying at 80 DEG  C., or on other fibres followed by drying and heating at 110-130 DEG  C.; (2) a mixture of di-iso-propyl xanthogenic disulphide, butadiene, acrylonitrile and styrene is emulsified in an aqueous solution of the sodium salts of sulphonated and sulphinated long chain paraffins, cetyl alcoholethylene oxide reaction product and potassium persulphate, and the emulsion is acidified and polymerized.  To the polymer emulsion thus obtained is added a formaldehyde conversion product of o-cyclohexyl-p-cresol, an aqueous solution of the basic polymer from dipropylene triamine, g ,g 1-diaminopropylmethylamine and hexane diisocyanate, an aqueous solution of the hydrochloride of a basic polymer from dipropylene triamine and epichlorohydrin, acetic acid, a pigment dye, urea, isooctyl alcohol and an aqueous benzine emulsion, and the paste so obtained is printed on cotton; (3) a copolymerized latex from dichloroethene and acrylic acid butyl ester is mixed with benzyl-p - hydroxy - diphenyl polyglycol ether, an aqueous solution of the acetate of a basic polyoxamide from diaminopropyl tetramethylene diamine and oxalic ester, an aqueous solution of the hydrochloride of a basic polymer from diaminopropyl tetramethylene diamine and epichlorohydrin, glycerol, methyl cellulose and copper phthalocyanine, and the paste so obtained is printed on cotton or rayon.  Specification 774,101 also is referred to.ALSO:The textile printing paste of the parent Specification comprising an emulsion of a vinyl or divinyl polymer or copolymer and a high molecular basic compound, together with a compound containing two or more groups capable of reacting with the basic groups of the high molecular compound, is modified by employing as the compound containing two or more reactive groups, a basic high molecular weight compound containing amino and/or imino groups and epoxy groups.
